Research And Development Of Fixed Assets Management System Based On RFID

With China's economy into the fast lane,the scale of the enterprise expands gradually,its fixed assets increased gradually.As one of the most important assets,fixed assets have many characteristics,such as high value,complex structure and so on.However,the managers of the enterprise tend to focus on the profit of the products and the working efficiency of the employees,but do not pay enough attention to the management of fixed assets,which leads to its management challenges.How to manage the fixed assets in real time and efficiently is an urgent problem to be solved.In view of the current situation of fixed assets management,this thesis presents a management system based on radio frequency identification technology,RFID technology is applied to the management of fixed assets,to achieve automatic management.This thesis mainly completes the following work:(1)A fixed assets management system based on RFID is proposed.This thesis analyzes and studies the theory and the current situation of fixed assets management.According to the lack of fixed assets management,the thesis presents the application of RFID technology in fixed assets management in order to improve the efficiency and management level of fixed assets management.The thesis selects the appropriate security method to ensure the safety of fixed assets information from the practical application.(2)An improved LANDMARC indoor localization algorithm based on Lagrange interpolation is adopted.The thesis analyzes the influence factors of indoor positioning,studies and summarizes several common indoor positioning methods.On this basis,the LANDMARC location algorithm based on RSSI value is analyzed.Aiming at the problems of the algorithm,the thesis compares and analyzes the positioning algorithm based on Lagrange nonlinear interpolation.It is proved that the algorithm can improve the positioning accuracy through MATLAB simulation.(3)This thesis designs and implements the system.By understanding the needs of users through on-spot investigation and with the existing management system the thesis analyzes the requirements and designs the system.The system is divided into eight function modules: information management,requisition and return management,allocation management,waste management,maintenance management,reportmanagement,inventory management and system management.The system is developed based on ASP.NET platform,by using B/S three layer architecture model.Based on the demand of fixed assets management,the system is designed.Compared to the original offline version management system in an enterprise,it has many advantages: by using B/S mode,it is easy to maintain;by using RFID automatic identification technology,it is conducive to automated inventory management;the application of RFID indoor positioning technology in fixed assets,and by sending a warning message for illegal mobile situation management,it can be propitious to reduce the loss of fixed assets.After trials in management work of the fixed assets in a certain enterprise,the system realizes the information management of the important process in the whole life cycle of the fixed assets equipment,achieves the desired results.
